List comprehensions: Difference between revisions

Perl 6Raku has single-dimensional list comprehensions that fall out naturally from nested modifiers; multidimensional comprehensions are also supported via the cross operator; however, Perl 6Raku does not (yet) support multi-dimensional list comprehensions with dependencies between the lists, so the most straightforward way is currently:

Note that <tt>gather</tt>/<tt>take</tt> is the primitive in Perl&nbsp;6Raku corresponding to generators or coroutines in other languages. It is not, however, tied to function call syntax in Perl&nbsp;6Raku. We can get away with that because lists are lazy, and the demand for more of the list is implicit; it does not need to be driven by function calls.
